Antoine Pitrou commented on ARROW-2193:
---------------------------------------
Ok, this is because I recently switched from gcc-4.9 to clang-5.0. With gcc,
plasma_store doesn't have a runtime dependency on boost:
{code:bash}
$ ldd `which plasma_store`
linux-vdso.so.1 => (0x00007ffc8b318000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0
(0x00007fdc79bbe000)
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6
(0x00007fdc7983c000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fdc79533000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1
(0x00007fdc7931d000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fdc78f53000)
/lib64/ld-linux-x86-64.so.2 (0x00007fdc79ddb000)
{code}
But with clang I get:
{code:bash}
$ ldd `which plasma_store`
linux-vdso.so.1 => (0x00007fff21ba4000)
librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f0d04d5d000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0
(0x00007f0d04b40000)
libboost_system.so.1.66.0 => not found
libboost_filesystem.so.1.66.0 => not found
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6
(0x00007f0d047be000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f0d044b5000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1
(0x00007f0d0429f000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f0d03ed5000)
/lib64/ld-linux-x86-64.so.2 (0x00007f0d04f65000)
